  1. Hi, I know this is an old thread, but still high in Google searches related to GGZ file format. Anyway, the four bytes in the .sum file aren’t checked by the GPS, so edit away! Perhaps it is checked, along with the basemap & preloaded map .sum files when the device is started in test mode, so Garmin service can tell the files are corrupt, and then rewrite them if that is the case.
  2. Ok, well open one of your archived tracks from the saved tracks in the menu, go sideways to view the elevation profile for the track, then exit back out with the quit button twice, and see if the unit turns off. Apparently it doesn’t happen for everyone, and it won’t happen if you entered the menu from any screen other than the map screen. I’m not so interested in geocaching, but wonder if the geocache database can simply be copied from a 64st or similar. This will be old, I know, but I’m guessing the preloaded data wouldn’t be tied to a specific unit, and would work.
  3. That explains things. I can’t say I’ve ever set up a route ahead of time for any hike on foot, so wouldn’t know. It was the Oregon 3D view I thought you were talking about, which was actually something I was hoping to see, but I was unaware it had been removed, so I guess there’s no chance of that.
  4. Hi, How do you see the elevation profile of the route ahead of you? The 66 doesn’t have the 3D view that the Oregon has AFAIK. Or are you talking about something else? I don’t see basemap shading on anything because it’s turned off in night view, which I use for everything, otherwise the other menu screens are ghastly.
  5. The Birdseye imagery was downloaded with Basecamp with a 64st connected. The imagery isn’t locked to a device until it’s sent from your PC to a device. The same is stated at the end of this document: https://www8.garmin.com/maps/birdseye/pdfs/BirdseyeUsersGuide_EN.pdf I used previously downloaded data and sent to the 66 from there. It makes no difference though (although I initially thought otherwise) if imagery is enabled or not. The issues with panning a map at low zoom, or this one above happen just the same. If Birdseye imagery isn’t valid for a device (if it were just copied from SD card of another unit), it simply doesn’t work, and you also get a warning of this at startup. For improved sensitivity, and some of it’s inherent quality, in the end, amounts to better accuracy. I’m sure Garmin would if it weren’t for the sacrifice. For GPS, and just about any other sat antenna, they are better in every way. Easy to observe with any GPS module that allows you to switch between multiple antennas.
  6. The bug I’m experiencing with the recording menu, I’ve nailed down to the elevation profile display. When I got it to record a short track, you can also go into saved tracks, and similarly move sideways through some information screens about the track, one of which is an elevation profile. Any playing around in that screen works, but powers off once exiting the menu back to the usual map view.
  7. My 64st and 66st both came preloaded with Top Australia and NZ V5 Lite, which is interesting, because V6 became available some months before the 66 was available. They are both the same file size, and the 64 can find an address with only the V5 lite map enabled (just tried today), where the 66 could not. I haven’t checked the 66 again since address search started working with it. For the 64, it may not go to the actual street address number I specified, but it does display the correct street in a map view.
  8. That video is probably mine. I made a bad call on the QFH antenna early on, but think it was fair, given it’s also the first time Garmin hasn’t specifically used it as a selling point. If it was shown definitely not to have one, I’d have taken it back for a refund for sure. I think one of the videos makes it clear why, and I have other GPS units with exchangeable antennas to compare various antennas for the same GPS device. Just tried again today, and moving the map at low zoom froze it so batteries had to be removed, and going into the recording menu, and moving left to see the altitude profile caused it to power off once that menu was exited (as it always does for me). There’s an error log file in the device’s storage that is appended with errors, but the register values are always all zeros, so I don’t suppose it’s useful debug info to sent to Garmin. Funny enough address search using the “find” button started working, but I don’t know if I did anything differently. Even if I was using the built in lite version topo map with no auto routing, I’d still expect to be able to find an address, and just not be able to route to it. In one case it did work, it did power off while routing to a found address though, or immediately after calculating the route). Totally off topic: A thought occurred to me. E-paper displays! Even if it meant a GPS mapping device was monochrome, wouldn’t E-paper display make the ultimate outdoor GPS?
  9. Hi To be honest, more often than not, mine just turns off by itself, but occasionally, and especially that time int he car, it freezes and needs batteries removed. There’s more than one way I can make it turn off, and one of those is to zoom out pretty far, and then I won’t be able to move the map with the D pad much until it powers off. I’d like to see the 3D view implemented for DEM maps as the Oregon has, but not before they fix what is done so far. The size, I’m used to GPSMAP 6x series for years, so it’s a different feeling holding this. The GPSMAP 6x with no attachments (but slip case) I’d call real comfortable to grip, but I understand anyone who would prefer the larger screen anyway. I wouldn’t though. I’d rather the hardware essentially the same, but shrunk down to usual 6x size, and still to have the usual slip case available (which doesn’t appear to be happening for 66).
  10. Hi, The current device firmware for GPSMAP 66 is version 2.10. The GPS chipset latest firmware is 2.50 at the time of writing this post. The GPS chipset firmware has nothing to do with the unit’s mapping or GUI. The GPS chipset updates: 2.40: Improved overall GPS positional accuracy. 2.50: Improved GPS performance in Expedition mode. https://imgur.com/a/sFD45JG https://imgur.com/a/7msQE3j None of you will see my posts for another three weeks. I’m probably wasting my time but anyway... It still just crashes all the time in a manner that turns itself off, or requires you to pull the batteries out to reset it or it stays frozen on a screen. Last night was the first time I took it in a car just to see a moving map. I had Dad driving for 20 minutes so I could play with it, and didn’t see a map at all until we were home again. It froze at the “Loading Profiles” screen three times, and each time I had to pull the batteries out. If it freezes while it’s making a beep sound, then that sound is continuous until you take the batteries out. Most annoying. I have Garmin original SD Card with preloaded Topo Australia V6 map (no firmware hacking or pirated maps). Yes it has micro USB, with enough potting compound surrounding it to suspect they could have fit mini USB, Yes there is a PCB image circulating to suggest it does have a QFH antenna, no a QFH antenna is not a placebo. It has qualities making it very suitable for GPS, such as circular polarisation, and inherent rejection of reflected signals originating from below the horizon. The display is larger, and more vivid, but the unit is larger, and feels larger in your hand. It may not be as comfortable to hold for long periods. In my view, it’s a paperweight, at least until it has some work to it’s device software. I’d by no means trust it to even maintain a track log for a long hike without just turning off, or freezing. Cheers.
  11. The Chirp beacon itself is a Texas Instruments MSP430 16 bit low power controller, and NRF24L01 2.4GHz transceiver. It can potentially communicate between 250kbps & 2Mbps. Parts are stock, and very easy to come by. In theory, they could easily be reproduced, but reversing would be very difficult.
